Application filed June 28, 19.09. Serial No. 504,722.

This invention relates to car axle box lids,

and has for its object to improve the same in the several particulars hereinafter noted.

The invention consists of the novel devices and combinations of devices hereinafter described and defined in the claims.

In some respects this invention is inthe nature of an improvement on the car axle box lid disclosed and claimed in Letters Patj ent of the United States, reissue to A. C. McOord, of date February 7,1899, under Reissue No. 11,716, and in other respects it IS in the nature of an improvement on the devices disclosed and claimed in Letters Patent No. 803,155, granted to W. G. Dunham,

of date October 31, 1905, entitled Car axle box lids. In the said prior McCord patent, the lid is connected to a hinge lug on the box, by trunnions arranged to engage elongated seats in said lug, and these seats are provided with entrance channels extending to the rearof the lug. The said rearwardly opening entrance channels were found to be objectionable in that they allow the admis' sion of dirt into the top of the box. In this improved lid construction, the lid is provided with a journal for cooperation with a seat in the hinge lug of the box, and this journal seat is provided with an upwardly extended entrance channel that is preferably always covered by a hood or upper end portion of the lid, so that no dirt can enter the box therethrough. Preferably the lid journal is afforded by axially alined, ut laterally spaced trunnions cast integral with the lid, and theseats and entrance channels therefor, are formed in the sides of the hinge lug, so that said journal is adivided or duplicate structure.

By flattening the journal or trunnions or making the same segmental instead of cylindrical in cross seotion, it is possible to make the entrance channel or channels therefor narrower than the greatest diameter of the said trunnion -.or journals, and thus to positively prevent the lid from becoming unseated, except when turned or forced to one position, and which position the said journal or trunnion will never assume when the lid is being operated.

' In the accompanying drawings which illustrate the invention, like characters indi cate like parts throughout the several views.

Referring to the drawings: Figure 1 is a view chiefly in front elevation, but with some parts broken away, and with some parts sectioned on the line ca -50 of Fig. 3; Fig. 2 is a fragmentary view in front elevation, showing a portion of the box and a'port-ion of the plunger stern of the lid closing device, the lid being removed; Fig. 3 is a vertical section taken on the line w m of Fig. 1, showing the lid closed, some parts being broken away; Fig. 4 is a view corresponding to Fig. 3, but showing the lid opened up; and Figs. 5 and 6 are fragmen-' tary views in section, respectively, transversely and longitudinally of the box, illustrating a slightly modified construction.

The numeral 1 indicates an axle box of standard construction, but which at its upper portion adjacent to its mouth opening 2, is formed with a heavy hinge lug 3 having vertically elongated trunnion seats 4 inits sides. The trunnion seats 4 are provided with upwardly extended trunnion entrance channels 5, and just to the rear thereof, it is formed with an upwardly extended lock shoulder 6. The lug 3, on its outer surface, is provided with laterally spaced flanges 7 formed on their faces with relatively small trunnion seats 8, having contracted forwardly extended entrance passages 8 The lid '9 which is preferably a malleable iron or steel casting, is formed at its upper portion with a central pocket 10 that bulges outward and embraces the hinge h1g3 of the box. On its sides, the pocket 10 is formed with axially alined inwardly projecting trunnions 11 shown as cast integral therewith. These trunnions 11 are flattened or made segmental, and are of such dimen-- sions that they can be passed through the entrance channels 5 of the hinge lug 3, only when the flattened sides of said trunnions are turned into alinement with the said channels. When the lid is closed, the upper rear edge 12 of the hood 10 engages the shoulder 6 of the 111g 3, and a lock flange 13 on the said lid engages with a rib 14 the perforated portion of the lid lug 15 formed at the lower edge portion of the box opening 2, and thus the lid is held in its locked position in 'such manner that it can be moved into its open position only by a combined siiding and pivotal movement.-

The lid 8, on its inner face, has an integrallyv cast or otherwise rigidly secured perforated bearing lug or bracket 15, through which the. stem of a T bolt 16 works freely. The

head of the T bolt 16 is formed at its ends with flattened trunnions 17 that are adapted to'be moved into the trunnion seats 8 of the lug 3, and to be interlocked therewith by rotation. A spring 18 surroundsthe stem .of the T bolt 16, and is compressed between and acollar 19 on the said T.bolt.

that when the lid is closed, the spring 18- By reference to Fig. 8, it will be noted,

thrown to the other side of its dead center,

and .then exerts a force which-yieldingly I holdssaid lid in its openposition. When the lid is in its open position, its trunnions 11 are moved into the upper extremities of the trunnion seats 4, but said trunnions are then turned into a position in which their greatest diameter is transverse of the entrance channels 5, and hence, cannot be removed through the said channels. When the lid is in its'closed position,; the spring 18 holds the trunnions 11 in the lower p'or-' tions of the said trunnion seats 4, so that it is not possible at any time for the lid to ".become accidentally detached from the box,

engagement of the upper edge 12 of the but it will be noted by reference particularly to Fig. 3, that when the lid is in a closed position, it is supported from the box,

against the tension of the spring 18, in

such a manner that the flattened journal 11 will beheld slightly above thevbottom of the seat 4. In practice, the lid when thus seated, maybe supported by engagement of the lid flange 13 with'the box rib 14, or by lid hood with the hinge lug; or this engagement made between the lid and box may be simultaneously at both points, or,

for that matter, at some other point. The gist of this arrangement is that when the lid is closed, it is seated on the box in such manner that wear will not then be upon the lid journal. When the lids-are mallea ble castings with integral journals, this arrangement for preventing wear on the lid journal when the lid is closed is especially important. To detach the lid from the box, it is necessary to slide the lidupward on the face of the box against the tension of the spring 18, far enough to force the trunnions 11 upward and outward through the entrance channels 5, and this, asisevident, requlres very considerable force. "When the 12 of the lid hood 10 rides on the rounded back portion of the hinge lug 3, but as preferably constructed at all times, the said hood covers the entrance channels 5, so that no dirt can enter the box therethrough.

lid is in its open position,the rear edge- In the construction illustrated in Figs. 5

and 6, the hinge lug 3 is provided with a journal seat 4 having an entrance channel 5%, that extends entirely through the said lug; and the lid 9 is provided with a flattened journal or shaft 11*, which latter is shown as cast integral with the said lid, but which might be a separately formed ation of this modified'arrangement is the same as that of the above described construction, wherein the journal on the lid is formed by the flattened trunnions 11.

What I claim is:

1.- The combination with an axle box and a lid hingedthereto, one of said members having a journal seat with an entrance channel leading thereto, and the other member having a journal insertible into said seat.

through said entrance channel, the said journal and seat connecting said lid to said box with freedom for pivotal and sliding part suitably connected thereto. The oper- I movements of the lid in respect to the box,

a spring reacting against said lid and box,

movable from ong side to'the other of a' dead center, and when the'lid is closed, ex-

trance channel, when the lid is in a pre determined position, the said lidchaving a sliding, as-well as a pivotal movement, and a spring re-acting against said lid and box, movable from one side to another of a dead center, and when the lid is closed, exerting a downward force thereon, tending to move the flattened journal thereof downward in said seat and away from said contracted entrance channel.

3'. The combination with an axle box and a lid hinged thereto, saill box having a hinge lug provided withv a seat formed with a contracted upwardly extended entrance channel, of a lid provided with a flattened jour-' nal insertible into said seat through said contracted entrance channel, when the lid. is in a predetermined position, the said lid having a sliding as well as a pivotal movement, and a spring reacting against said lid and box, movable from one sideto'the iso 7 on, tending to move the flattened journal thereof downward in said seat and away.

from said contracted entrance. channel, said lid having a hood that covers said entrance i flattened journal,

4. The combination with an axle box having a hinge lug formed with. a seat and with a contracted upwardlyextended entrance channel thereto, of a' lid provided with'a iilsertible into said seat through said contracted entrance channel,

when said lid is turned into a predetermined position, said lid having'a hood portion engage'able withsaid hinge lug and arranged always to cover said entrance channel, the

said lid being free for pivotal-and sliding movements and'having a part arranged to interlock with the box by sliding movement, and a compression spring reacting against said lid and-box, movable from one side to the other of a dead center and tending to hold said lid in its closed or open position,.

depending on the position in which the lid is set.

In testimony whereof I afix my signature in presence of two witnesses.
